3、牽引變電(dian)模(mo)型(xing)

    沙盤設置2個牽引變電所（1#、2#）、1個開閉所（主供車站2#側(ce)線）、2個分(fen)區所；采用彩色有機玻璃雕刻技術，來模擬牽引變電所的房屋。

4、微(wei)機聯鎖及(ji)牽(qian)引供電系(xi)統(tong)操(cao)作臺(tai)

       系統實(shi)(shi)現牽引變(bian)電(dian)所(suo)(suo)、開閉所(suo)(suo)、分區所(suo)(suo)的計(ji)算(suan)機綜合控(kong)制功能。利(li)用計(ji)算(suan)機控(kong)制軟(ruan)件實(shi)(shi)現對牽引供(gong)電(dian)的控(kong)制。真(zhen)實(shi)(shi)再現牽引供(gong)電(dian)在(zai)不同運(yun)行方(fang)式和運(yun)行狀態下控(kong)制及操作功能，通過軟(ruan)件界面實(shi)(shi)現真(zhen)實(shi)(shi)供(gong)電(dian)系統的調度仿真(zhen)。
